It is welded to connect, i.e. sweat soldering connects, and its operation is more complicated, it is necessary to which certain operative skill and practical experience, other are several
Mode there is also complicated or reliability it is not high the drawbacks of.
The content of the invention
The present invention is for defect problem present in above-mentioned prior art, there is provided a kind of quick, effective, reliable plastic tube
With no-welding snap joint, by setting anti-slop serrations and sealing ring on semicircular shell opposed up and down, pass through rubber and pipeline
Friction and anti-slop serrations double action, be securely attached together two pipelines.
To achieve the above object, the technical solution adopted by the present invention is：
A kind of no-welding snap joint of plastic tube, including fast section, sealing ring, pipeline up and down；The section fast up and down is half
Circular shell, housing body cross sectional shape are U-shaped, and semicircular shell root is provided with ear connecting portion, and ear connecting portion is drilled with
Through hole, fast section up and down is linked together by bolt, cladding 2-section pipe road is integral；The sealing ring be arranged on up and down section with
Between pipeline, sealing ring main body is half-circle-arc shape, and main body section is L-shaped dentation, dentalation lip fitting pipeline, passes through tooth
Sealing function is played in the deformation of shape structure lip, is securely attached together two pipelines.
Further, the section fast up and down is connected by articulated manner.
Further, it is described that anti-slop serrations are installed between section and pipeline up and down.
Further, the anti-slop serrations are semi arch U-shaped structure, and main body section is U-lag, and U-lag is entrenched in fast up and down
Save outside semicircular shell U-shaped section on incline plate；The cambered surface of anti-slop serrations U-lag back side fitting pipeline is provided with dentation.
Further, the dentation is triangle barb-shaped or columnar protrusions or granular projection.
Beneficial effects of the present invention：A kind of no-welding snap joint of plastic tube, pass through semicircular shell opposed up and down
Upper setting anti-slop serrations and sealing ring, by the friction of rubber and pipeline and the double action of anti-slop serrations, make two pipelines securely
Link together；Efficiently avoid pipeline expand with heat and contract with cold or other external factor under the influence of transverse direction detach effect；Have
The characteristics of quick for installation, efficient, reliable.

Embodiment
In order that the technical means, the inventive features, the objects and the advantages of the present invention are easy to understand, tie below
Conjunction is specifically illustrating, and the present invention is expanded on further.
When it is implemented, with reference to shown in Fig. 1, a kind of no-welding snap joint of plastic tube, including fast section 1, sealing up and down
Circle 2, anti-slop serrations 3, pipeline 4.
With reference to Fig. 2, fast section 1 is semicircular shell up and down, and housing body section 6 is shaped as dual U-shaped, semicircular shell root
Portion is provided with ear connecting portion 5, and ear connecting portion 5 is drilled with through hole, and fast section 1 up and down is linked together by bolt, cladding two
Length of tubing 4 is integral.Fast section 1 may be designed as radial type connection or other connected modes up and down.
With reference to Fig. 3 (a), (b), sealing ring 2 is double semicircular arc structures, and sealing ring main body 7 is half-circle-arc shape, its section
8 be L-shaped dentation, dentalation lip fitting pipeline 4, sealing function is played by the deformation of dentalation lip, meanwhile, dentation
Structure can be effectively anti-skidding, is securely attached together two pipelines.
With reference to Fig. 4 further to increase skidproof effect, anti-slop serrations 3 are additionally arranged.Anti-slop serrations 3 are semi arch U-shaped knot
Structure, main body section 9 are U-lag, and its U-lag is entrenched in up and down soon outside 1 semicircular shell U-shaped section of section on incline plate.
The anti-slop serrations 3U shape grooves back side is that the cambered surface for being bonded pipeline 4 is provided with dentation 10, and dentation 10 is triangle reverse
Shape is pierced, as shown in figure 4, anti-slop serrations 3 are right side antiskid tooth, right side anti-slop serrations and right side antiskid tooth are symmetrical.The triangle of dentation 10
Two connecting end surfaces in hangnail tip point tube road 4, i.e. the triangle glochidium portion of dentation 10 point to two pipes with being connected
Road 4 laterally detaches direction in opposite direction.Pipeline 4 is tightly coated with after being deformed by radial force, is further increased
Skidproof effect, efficiently avoid pipeline 4 expand with heat and contract with cold or other external factor under the influence of transverse direction detach effect.It is anti-skidding
The main body section 9 of tooth 3 may be designed as other forms, L-shaped as shown in Figure 5.Dentation 10 may be designed as other forms,
Post holes shape projection as shown in Figure 6, granular projection as shown in Figure 7.
The present invention passes through rubbing for rubber and pipeline by setting anti-slop serrations and sealing ring on opposed semicircular shell up and down
The double action with anti-slop serrations is wiped, is securely attached together two pipelines；Efficiently avoid expand with heat and contract with cold in pipeline or
Transverse direction under the influence of other external factor detaches effect；With it is quick for installation, efficient, reliable the characteristics of.
The above-described embodiments are merely illustrative of preferred embodiments of the present invention, not to the structure of the present invention
Think and scope is defined.On the premise of design concept of the present invention is not departed from, technology of the ordinary people in the field to the present invention
The all variations and modifications that scheme is made, protection scope of the present invention all should be dropped into.
